  1. Figure shows aggregate double decomposition of changes in the Gender Pay Gap (GPG) in West Germany. Estimation based on approach outlined in Sect. 3. Men in 1984 used as reference category. \(\Delta\) refers to the aggregate change in percentage points in the GPG 2020-1984 in West Germany. Change in Explained refers to the corresponding change in the quantity effect. Change in Unexplained refers to the change in the price effect. \(\hat{\alpha }_1^{base}\) and \(\hat{\alpha }_1^{full}\) are the coefficient estimates of Female X Year from the base and full regression, respectively. Female X Year is an interaction between the female and 2020-year dummy. See Table 4 for the corresponding regressions at the mean. Set of controls includes: quadratic polynomials of full-time experience, job tenure, past part-time experience (controls in years), as well as dummies for highest educational attainment, age, marital status, migration background, having at least one child, having at least one child below the age of 2 years and between two and six years, respectively. Further, the following dummies are included: occupations (ISCO-88, 1-digit) and industries (NACE, level 1), small (\(<200\) employees) and medium (\(200-1999\) employees) firm size as well as public-sector firm, respectively. Federal state fixed effects included. Robust (for the mean) and bootstrapped (for the estimates beyond the mean, 500 replications) standard errors in parentheses. \(*** p<0.01\), \(** p<0.05\), \(* p<0.1\). SOEP sample weights used.
